Version 7 and we're just now getting the ability to sideload without a developer license? I think that actually demonstrates the PP's point. This isn't a new liberty, this is a tool to help Apple to drive adoption of their new language.
Their point was that the ability is going to be removed if it gets used at all. That just doesn't make any sense given the fact I outlined in my response.
In fact, Apple even advertises this ability as the most prominent new feature of Xcode 7.[1]
If your response were true, Apple would never have added this ability in the first place.
